A DDR5 RDIMM (Registered Dual In-line Memory Module) is a server-class DRAM module that places a register clock driver (RCD) between the DRAM chips and the memory controller, electrically buffering address and command signals so the controller can drive many modules per channel. RDIMMs sit within the broader DRAM module hierarchy (UDIMM < RDIMM < LRDIMM), with ECC RDIMM further adding on-die plus side-band error correction to meet RAS (Reliability, Availability, Serviceability) targets demanded by data-center workloads.
Key features include a transfer rate of 5600 MT/s (PC5-44800), a CAS latency of CL46, on-module ECC with x80 organization, 1.1V VDD operation per JEDEC DDR5 specification, and a 288-pin edge-finger connector compliant with the DDR5 RDIMM mechanical outline. The 2Rx4 dual-rank x4 architecture maximizes channel parallelism for higher sustained throughput at matched timings.
Architecturally, the module integrates the RCD, a 12V-tolerant PMIC for on-module voltage regulation, a SPD/TS hub for device identification and thermal telemetry, and eight 8Gb DDR5 SDRAM components organized x4 with on-die ECC. Registered buffering enables stable multi-module-per-channel operation (typically 2 DPC) without the signal-integrity loss seen with unbuffered modules.
Typical applications include hyperscale and enterprise servers (1-socket, 2-socket, 4-socket), AI training and inference nodes requiring high-capacity registered memory, virtualization clusters with high VM densities, in-memory databases (SAP HANA, Redis), and workstation platforms built on Intel Xeon Scalable or AMD EPYC processors. The 64GB density and 1.1V operation also support thermal-constrained 1U and 2U chassis.
When designing, verify BIOS / firmware RC code compatibility with the SKU's SPD profile, confirm the 2Rx4 rank configuration is supported on the target board, and observe airflow requirements for the 1.1V, 5600 MT/s power envelope.

Tipikal na mga Gamit
MTC40F2046S1RC56BD1 ay nararapat para sa 7 aplikasyons: Enterprise Rack Servers (1S / 2S / 4S), AI Training and Inference Nodes, In-Memory Databases (SAP HANA, Redis), Virtualization and VDI Clusters, Workstation-Class Compute Nodes, Hyperscale and Cloud Compute Instances, Data Analytics and Hadoop-Class Clusters.
Enterprise Rack Servers (1S / 2S / 4S)
The MTC40F2046S1RC56BD1 fits 1U and 2U enterprise rack servers where 64GB per DIMM slot halves the module count needed versus 32GB modules, leaving slots free for future expansion. Its 2Rx4 dual-rank organization maximizes channel parallelism at 5600 MT/s, delivering the bandwidth that Xeon Scalable and EPYC 9004-class CPUs need for virtualization, container hosts, and consolidated database workloads. The on-module PMIC and register clock driver ensure stable 2-DPC operation without manual tuning.

AI Training and Inference Nodes
AI training and inference nodes built on multi-socket EPYC or Xeon platforms demand large per-socket memory capacity to host model weights, KV caches, and feature stores. The MTC40F2046S1RC56BD1's 64GB density and 5600 MT/s bandwidth let a single 2-socket node host tens of GBs of model state per socket, while ECC protects against silent data corruption during long-running training jobs. Its 1.1V operating point also eases thermal envelope compliance in dense GPU-adjacent server chassis.
Inirekomenda
In-Memory Databases (SAP HANA, Redis)
In-memory database deployments such as SAP HANA, Redis Enterprise, and TimescaleDB scale out primarily through per-socket memory capacity, where 64GB DDR5 RDIMMs like the MTC40F2046S1RC56BD1 minimize DIMM slot consumption while maximizing usable heap. The 5600 MT/s transfer rate sustains high random-access throughput, while CL46 keeps latency predictable for OLTP-grade query paths. Registered buffering and on-module ECC provide the RAS guarantees financial and analytics deployments require.
Inirekomenda
Virtualization and VDI Clusters
Virtualization and VDI clusters pack hundreds of VMs or persistent desktops onto a single host, so memory oversubscription pressure must be absorbed by high-density, registered modules. The MTC40F2046S1RC56BD1 at 64GB per slot gives hypervisors like VMware ESXi, Hyper-V, and KVM the headroom to run larger VM pools without ballooning or swap. JEDEC-compliant 1.1V DDR5 operation integrates with standard server power budgets and firmware SPD tables.
Inirekomenda
Workstation-Class Compute Nodes
Single-socket and dual-socket workstation-class nodes built on Xeon W or Threadripper Pro platforms need ECC RDIMMs to qualify for professional CAD, EDA, and content-creation ISV certifications. The MTC40F2046S1RC56BD1's 64GB capacity and 5600 MT/s bandwidth give EDA simulation and high-resolution video timelines the working-set headroom they require. The 288-pin RDIMM form factor matches standard workstation board memory slots with no firmware workarounds.
Inirekomenda
Hyperscale and Cloud Compute Instances
Hyperscale and cloud compute providers standardize on 64GB DDR5-5600 ECC RDIMMs because they optimize the density, throughput, and $/GB trade-off for general-purpose VMs. The MTC40F2046S1RC56BD1, built to Micron's JEDEC-compliant DDR5 RDIMM specification with on-module PMIC and SPD hub, drops directly into standard cloud-server SKUs without firmware retuning. Micron's DID-agnostic server program also means a compatible in-stock 5600 RDIMM can ship when the exact SKU is unavailable.
Inirekomenda
Data Analytics and Hadoop-Class Clusters
Apache Hadoop, Spark, and Trino clusters rely on large memory-resident datasets to accelerate shuffles, joins, and broadcast exchanges. The MTC40F2046S1RC56BD1's 64GB density and 5600 MT/s throughput reduce disk spill events during iterative analytics jobs, while ECC protects long-running shuffles from silent data corruption. Its 2Rx4 dual-rank topology complements the multi-channel memory controllers typical in 2-socket analytics nodes.

Talaan ng Disenyo
At 5600 MT/s, 1.1V VDD and typical 2Rx4 activity, the MTC40F2046S1RC56BD1 dissipates roughly 8-10W per module under sustained load. Ensure server airflow follows the platform's memory cooling guideline (typically 5-7 CFM per DIMM in a 2U chassis) and keep DIMM inlet air below 55C to avoid thermal throttling of the on-module PMIC. Avoid placing the module directly behind a hot-swap PSU or NVMe cage.
Do not mix the MTC40F2046S1RC56BD1 with LRDIMMs or 3DS modules in the same channel - the RCD training sequence assumes homogeneous rank geometry. Mixing dual-rank 2Rx4 with single-rank 1Rx4 modules in the same channel is allowed only when the BIOS explicitly supports the asymmetric population mode. Always update the platform's RC code to a version that lists this exact Micron SPD ID.
Populate DIMM slots in the order specified by the server vendor (typically slot 0 / slot 1 first per channel) to ensure proper RCD training. For maximum bandwidth on 2-socket platforms, balance the MTC40F2046S1RC56BD1 population equally across both sockets and across the memory channels of each socket to enable the platform's interleaving mode.
